Abstract
Abstract A meat tenderizing apparatus, particularly but not exclusively for meat that contains bones, in which force yieldable sets each containing a plurality of elongated knives are used so that the stress on each knife is reduced to a safe level. Each knife has a sharp meat penetrating end and each set comprises a shank or piston and a plurality such as a pair of knives mounted on the shank with the knives in each set parallel and closely spaced and with the meat penetrating ends of the knives in each set being adjacent to but separate from each other so that the progress into the meat of the knives is stopped when at least one knife of a set strikes a bone.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A yieldable-knife meat tenderizing apparatus particularly for meat that contains bones, comprising: a plurality of closely spaced, force yieldable sets of elongated knives with each knife having a sharp meat penetrating and meat severing sloped end, each said set comprising a reciprocable piston and a plurality of said knives on the piston with the knives in each set being substantially parallel to each other and to their said piston and with the meat penetrating ends of the knives of each set being adjacent to but separate from each other; and force yieldable means independently retaining each said set of elongated knives in meat penetrating position.
Claim 2
Dependent Claim
105 words
A yieldable-knife meat tenderizing apparatus particularly for meat that contains bones, comprising: a plurality of closely spaced, force yieldable sets of elongated knives with each knife having a sharp meat penetrating and meat severing sloped end, each said set comprising a reciprocable piston and a plurality of said knives on the piston with the knives in each set being substantially parallel to each other and to their said piston and with the meat penetrating ends of the knives of each set being adjacent to but separate from each other; and force yieldable means independently retaining each said set of elongated knives in meat penetrating position.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein there are provided a pair of said knives in each said set on diametrically opposite sides of their said piston.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 wherein said force yieldable means comprises pneumatic pressure means for acting against said piston.
Claim 5
Dependent Claim
32 words
The apparatus of claim 3 wherein said pneumatic pressure means is substantially equivalent in force to about 40 pounds per square inch gauge on a said piston of about 0.28 inch diameter.
Claim 6
Dependent Claim
25 words
The apparatus of claim 1 wherein the ends of the knives in each said set are substantially transversely aligned for simultaneous penetration of said meat.
